From Stephen Warren:

ARM: tegra: device tree changes

This branch adds two main features to Tegra boards, simply by amending
device tree files: regulator support and the ability to turn off system
power when executing "shutdown".

As part of these changes, the board file for Cardhu is split into two
versions, since different revisions have different hardware in some
areas, especially related to regulators.

* tag 'tegra-for-3.7-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra:
  ARM: dt: tegra: configure power off for some boards
  ARM: dt: tegra: whistler: add regulators
  ARM: dt: tegra: paz00: add regulators
  ARM: dt: tegra: ventana: add regulators
  ARM: dt: tegra: seaboard: add regulators
  ARM: tegra: cardhu: add dt entry for fixed regulators
  ARM: dt: tegra: cardhu: split dts file for support multiple board versions
  ARM: dt: tegra: cardhu: add entry for PMIC TPS65911.
